Free-agent DL Luis A. Castillo (Chargers) is trying to decide if he wants to continue his playing career or stop because of recurring back problems. Castillo will need a few weeks to get healthy if he decides to continue his playing.

The San Diego Chargers would like to re-sign free-agent DL Luis A. Castillo, who was released last week in a cost-cutting move. San Diego would like him to return at a cheaper price. The Chargers, however, may not be able to bring him back, as several other teams are showing interest.
